Every CryptoExpress engine has two identifiers: PCHID and number used in
ICSF panels.
Both identifiers can be seen in SE.
PCHID number is not available in ICSF (why???)
However I'm wondering how the crypto numbers are assigned.
PCHID - it is determined by location of the card, as well as FICON or
> OSA.
However I observed two machines with same number of CryptoExpress cards,
same PCHID numbers for the cards, but different crypto number
assignments. Both machines are z15, ordered, delivered and installed
together. No difference in model, microcode, features like FC 3863...
Any clue?
I did a bunch of asking around, combined all the answers, and then
paraphrased:
The IDs are assigned during the 1st power up, starting with the lowest
available ID. If I add cards via HOT plug, I can pick and choose IDs. It
depends on the exact hw that was plugged and in what order. FC 898 is 2
cryptos per card vs FC899 1 crypto per card
I think it doesn't work that way.
2 CPCs z15 T01. Each of CPC has 2 cards FC 0898 => 4 crypto engines per CPC.
Cards are located in same slots, and have same PCHIDs.
CPC A:
PCHID crypto #
15C 00
15D 01
12C 02
12D 03
CPC B:
PCHID crypto #
15C 00
12C 01
15D 02
12D 03
b
The possible scenario is "left card was inserted first in CPC A, but
last in CPC B" or "left card was inserted first in both CPCs".
It is impossible to have "crypto PCHID 15C was inserted first in CPC A,
but next one was PCHID 12C and then 15D and finally 12D".
In my humble opinion the order of cryptos or crypto-to-PCHID assignment
should be either predictable or preferably customizable.
Reason: when a card is replaced, both cryptos become unavailable. It is
good to know which ones. Of course it can be documented by the admin.
